Use a T-nut, or tee nut, from Grainger to fasten a wood, particle or composite materials workpiece, leaving a flush surface. T-nuts have a long, thin body and a flange at one end, so they look like a T in profile. The prongs on the flanges sink into the wood to hold it more securely. Choose from 3-prong and 4-prong tee nuts with the dimensions you are seeking. Trust Grainger for the T-nut or tee nut that will help you get the job done.
